Literatürde, dinamik yüklere maruz kalan bu tür kompozit kolon elemanlarının tepkisini modellemek için farklı doğrusal olmayan modelleme stratejileri için çeşitli çalışmalar yapılmıştır. Literatürde son yıllarda kullanılan ABAQUS, ANSYS ve LS-DYNA gibi bir sonlu elemanlar yöntemi kullanan yazılımlar ile beton dolgulu çelik tüp elemanlarına ait çalışmalarda, çelik ile beton bileşenlerin genellikle plaka, kabuk veya katı elemanların yardımı ile ayrı ayrı modellendikleri görülmektedir. Bu eleman modellerinin aralarındaki etkileşimi simüle etmek için bazı diğer bağlayıcı veya arayüz elemanlarının yardımına ihtiyaç duyulmaktadır. Dolayısıyla, ticari paketler kullanmanın en büyük dezavantajı, analitik olarak modellencecek elemana ait çok daha küçük parçalar kullanılarak ve bunlar arasında üretilecek olan etkileşim yapıları nedeniyle çok karmaşık hesaplamalar ortaya çıkmaktadır. Sonuç olarak hesaplama açısından yoğun ve aynı zaman uzun süreli çalışma gerekliliği ortaya çıkmaktadır. Bu çalışma kapsamında kompozit kolonların eksenel düşey etkiler altında fiber kesitli elemanlar ve standart malzeme modelleri kullanılarak daha hızlı ve mümkün olduğunca daha doğru hesaplanması hedeflenmiştir. Seçilen parametrelerin elde edilen sonuçlar üzerinde önemli derecede etkili olduğu gözlemlenmiştir.

Analytical Evaluation of Behavior of Composite Columns Under Axial Load

Öz

In the literature, various studies have been carried out for different nonlinear modeling strategies to model the response of such composite column members subjected to dynamic loads. In studies of concrete filled steel tubes elements with software using a finite element method such as ABAQUS, ANSYS and LS-DYNA, which have been used in the literature in recent years, it is seen that steel and concrete components are generally modeled separately with the help of plate, shell, or solid elements. To simulate the interaction between these element models, the help of some other connector or interface elements is needed. Therefore, the biggest disadvantage of using commercial packages is that very complex calculations arise by using much smaller parts of the element to be analytically modeled and the interaction structures to be produced between them. As a result, the necessity of computationally intensive and at the same time long-term work emerges. Within the scope of this study, it is aimed to calculate composite columns faster and more accurately as possible by using fiber section elements and standard material models under axial loading effects. It was observed that the selected parameters had a significant effect on the results obtained
